Application filed November 4, 1914. Serial No. 870,294.

To all whom it may concern Be it known that we, PETER RASMUSSEN andMAxonL F. GOULARTE, citizens of the United States, residing at Selma, inthe county of Fresno and State of California, have invented certain newand useful Improvements in Window-Operating Mechanism, of which thefollowing is a specification, reference being had tovthe accompanyingdrawings.

This invention relates to an improved window operating mechanism and hasfor its primary object to provide simple and eflicient means for movinga window sash, and retaining the same in a partly open position.

The invention has for a further object to provide a device of the abovecharacter which is so mounted and'arranged that ac cess may be readilyhad to the parts thereof when it is necessary to repair the same, the

device being simple and durable in its construction and capable ofmanufacture at comparatively small cost.

With the above and other objects in view, our invention consists in thenovel features of construction, combination, and arrangement of parts tobe hereinafter more fully described, claimed, and illustrated in theaccompanying drawings, in which,

Figure 1 is a side elevation of a window showing the sashes in partlyopen position, a portion of the removable section of the window framebeing broken away to show the operating mechanism; Fig. 2 is a sectiontaken on the line 2'-2 of Fig. 1; Fig.3 is an edge view of the window;Fig. 4 is a section taken on the line 44 of- Fig. 3.

Referring in detail to the drawings, 5 designates a window frame of anyordinary or approved construction which includes hollow vertical sidemembers 6, a lintel 7, anda sill 8. To the inner faces of the members 6,the vertically standing parting strips 9 are secured which are disposedbetween and separate the sashes 10 from each other. One of these innerwalls of the hollow side members of the frame is further provided anismfor the window sashes is arranged. Thls mechanism is mounted upon asuitable base plate 13 which is secured to the inner wall of the framemember 6. Upon this base plate, the longitudinally extending metal bars14 are secured, said bars being provided upon their opposite ends withbearing lugs 15. In the bearing lugs of each of the bars 14, theopposite ends of a vertically disposed shaft 16 are journaled, and tothe upper end of each shaft, a beveled pinion 17 is fixed. -Ahorizontally disposed shaft 18 is also mounted in the bearing on theupper end of each of the bars 14, and said shafts are provided uponrelatively opposite ends with the large gear wheels 19. Upon the otherend of each shaft 18, a ratchet 20 is secured. Each of the gears 19 isprovided upon its inner face with a beveled gear 21 which meshes withthe gear 17 upon one of the shafts 16. A coil spring 22 is arranged uponeach of these shafts and has its upper end fixed to the gear 17 and itslower end suitably secured to one of the bearing lugs 15. The base plate13 upon which the operating mechanism is mounted, is provided with alongitudinally extending slot 23 which coincides with a similar slotprovided in the inner wall of the side member 6 of the window frame.Through the slots, the respective gear wheels 19 extend and engage withthe racks 12 secured upon the respective window sashes.

24 designates the locking levers which are fulcrumed intermediate oftheir ends as at 25 and project outwardly through slots 26 in aremovable wall section 27 of the frame member 6. The inner ends of theselevers are laterally extending as at 28 and terminate in the downwardlyprojecting portions 29 which are adapted for engagement with the teethof the respective ratchets 20 to lock the shafts 18 against rotationunder the action of the springs 22. Each of the levers 24 is normallyheld in its locking position by means of a coil spring 30.

From the foregoingdescription, taken in connection with the accompanyingdrawing, the construction and arrangement of the several parts of ourinvention will be clearly and fully understood. When the lower sash ismoved from its open to its closed position,

the operator must first press upon the lowermost lever 24 to lift theinner end thereof,- from engagement with the ratchet 20. Thus, when thewindow sash is forced downwardly in the frame, the rack thereon meshingwith the gear 19, will rotate the lower vertical shaft 16 and place thecoil spring 22 under tension. When the upper sash is lowered to its openposition in the frame, the same action takes place. It will beunderstood that the sashes may be disposed in an intermediate positionat any desired point in order to properly ventilate the room orapartment, and are retained in such partially open positions by 'meansof the locking levers 24. When it is desired to elevate either of thesashes in the frame, the operator presses theproper lever 24 so that thespring 22 may act to rotate the shaft 16 and thus transmit rotation tothe gear 19. This gear meshing with the rack-l1, moves the sash, as willbe readily understood. It is, of course, obvious that by simplyreversing the direction of turn of the coils of either spring, the lowersash may be moved to its closed position under the action of the springor the upper sash moved to its open position instead of vice versa,asabove eX- plained.

By means of our invention, it will be appreciated that the sashes may bevery easily and quickly operated and the manual labor incident to theraising or lowering of the sashes, thus avoided.

The several parts of the mechanism are all of exceedingly simple formand may be manufactured and assembled in the window structure atcomparatively small cost.

While we have shown and'described the preferred construction 'andarrangement of the several elements employed, it will be understood thatthe invention is susceptible of considerable modification therein, andWe therefore reserve the privilege of resorting to all such legitimatechanges as may be fairly embodied within the spirit and scope of theinvention as claimed.

Having thus fully described our invention, what we desire to claim andsecure by Letters Patent is The combination with a window frame and sashmounted therein, of a base plate secured upon one side of said frame andprovided with spaced bearing lugs, said base plate and the frame havingcoinciding slots therein, a vertically disposed shaft journaled at itsends in said bearing lugs, a transversely disposed shaft rotatablymounted in one of the lugs above said vertical shaft, a coil springengaged upon said vertical shaft to rotate the same in one direction, abeveled gear fixed upon the upper ends of said shaft, a gear fixed uponone end of said transverse shaft and pro vided with a bevel gear ofrelatively small diameter meshing with the gear on the vertical shaft,said first named gear on the transverse shaft extending through theregistering slots in the base plate and the frame, a rack bar fixed uponthe sash and meshing with said gear, a ratchet secured upon the otherend of the transverse shaft, and a manually operable latch devicepivotally mounted upon the base plate and engaging at one end with saidratchet to normally hold the shafts against rotation under the action ofsaid spring.

In testimony whereof we hereunto aflix our signatures in the presence oftwo witnesses.
